Apple has never let outside developers inside the iPod party (the Nike+ kit was developed by Apple). I hope the iPhone isn’t a closed platform. By the look of the iTunes syncing interface for the iPhone, I can’t see a way to upload new apps. The Treo developer community is what makes the Treo such a powerful smartphone. There’s an app out there that does just about anything- including Excel and Word. The ability to have iPhone apps would allow this phone to truly be revolutionary. Worst case, it needs Java, but I’m not seeing a Virtual Machine button on any of the iPhone menus. And as Marty pointed out (and Palm has known until recently) without Exchange Server support it’s not a business phone.
